人胰高血糖素样肽1(GLP-1)酶联免疫分析（ELISA）试剂盒使用说明书
本试剂仅供研究使用
实验目的：本试剂盒用于测定人血清，血浆及相关液体样本中胰高血糖素样肽1(GLP-1)的含量。
实验原理：
应用双抗体夹心法测定标本中人胰高血糖素样肽1(GLP-1)水平。用纯化的人胰高血糖素样肽1(GLP-1)抗体包被微孔板，制成固相抗体，往包被单抗的微孔中依次加入胰高血糖素样肽1(GLP-1)，再与HRP标记的胰高血糖素样肽1(GLP-1)抗体结合，形成抗体-抗原-酶标抗体复合物，经过*洗涤后加底物TMB显色。TMB在HRP酶的催化下转化成蓝色，并在酸的作用下转化成zui终的黄色。颜色的深浅和样品中的胰高血糖素样肽1(GLP-1)呈正相关。用酶标仪在450nm波长下测定吸光度（OD值），通过标准曲线计算样品中人胰高血糖素样肽1(GLP-1)浓度。

样本处理及要求：
1. 血清：室温血液自然凝固10-20分钟，离心20分钟左右（2000-3000转/分）。仔细收集上清，保存过程中如出现沉淀，应再次离心。
2. 血浆：应根据标本的要求选择EDTA或柠檬酸钠作为抗凝剂，混合10-20分钟后，离心20分钟左右（2000-3000转/分）。仔细收集上清，保存过程中如有沉淀形成，应该再次离心。
3. 尿液：用无菌管收集，离心20分钟左右（2000-3000转/分）。仔细收集上清，保存过程中如有沉淀形成，应再次离心。胸腹水、脑脊液参照实行。
4. 细胞培养上清：检测分泌性的成份时，用无菌管收集。离心20分钟左右（2000-3000转/分）。仔细收集上清。检测细胞内的成份时，用PBS（PH7.2-7.4）稀释细胞悬液，细胞浓度达到100万/ml左右。通过反复冻融，以使细胞破坏并放出细胞内成份。离心20分钟左右（2000-3000转/分）。仔细收集上清。保存过程中如有沉淀形成，应再次离心。
5. 组织标本：切割标本后，称取重量。加入一定量的PBS，PH7.4。用液氮迅速冷冻保存备用。标本融化后仍然保持2-8℃的温度。加入一定量的PBS（PH7.4），用手工或匀浆器将标本匀浆充分。离心20分钟左右（2000-3000转/分）。仔细收集上清。分装后一份待检测，其余冷冻备用。
6. 标本采集后尽早进行提取，提取按相关文献进行，提取后应尽快进行实验。若不能马上进行试验，可将标本放于-20℃保存，但应避免反复冻融.
7. 不能检测含NaN3的样品，因NaN3抑制辣根过氧化物酶的（HRP）活性。
实验结果计算：
以标准物的浓度为横坐标，OD值为纵坐标，
在坐标纸上绘出标准曲线，根据样品的OD
值由标准曲线查出相应的浓度；再乘以稀释
倍数；或用标准物的浓度与OD值计算出标
准曲线的直线回归方程式，将样品的OD值
代入方程式，计算出样品浓度，再乘以稀释
倍数，即为样品的实际浓度。
试剂盒性能：
1.样品线性回归与预期浓度相关系数R值为0.92以上。
2.批内与批间应分别小于9%和13%
检测范围：
2pg/ml -100pg/ml
试剂盒保存：2-8℃
有效期：6个月

Purpose
This kit allows for the determination of GLP-1 concentrations in Human serum, blood plasma, and other biological fluids.
Principle of the assay
The kit assay Human GLP-1 level in the sample，use Purified Human GLP-1antibody to coat microtiter plate wells, make solid-phase antibody, then add GLP-1 to wells, Combined GLP-1 which With HRP labeled , become antibody - antigen - enzyme-antibody complex, after washing Compley, Add TMB substrate solution,TMB substrate becomes blue color At HRP enzyme-catalyzed, reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. The concentration of GLP-1 in the

- Urine-collect sue a sterile container, centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant, If precipitation appeared, Centrifugal again. The Operation of Hydrothorax and cerebrospinal fluid Reference to it.
- cell culture supernatant-detect secretory components, collect sue a sterile container, centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant,detect the composition of cells, Dilut cell suspension with PBS（PH7.2-7.4）, Cell concentration reached 1 million / ml, repeated freeze-thaw cycles, damage cells and release of intracellular components, centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant, If precipitation appeared, Centrifugal again.
- Tissue samples- After cutting samples, check the weight,add PBS（PH7.2-7.4）, Rapidly frozen with liquid nitrogen, maintain samples at 2-8℃ after melting,add PBS（PH7.4）, Homogenized by hand or Grinders, centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant.
- extract as soon as possible after Specimen collection,and according to the relevant literature, and should be experiment as soon as possible after the extraction. If it can’t, specimen can be kept in -20 ℃ to preserve, Avoid repeated freeze-thaw cycles.
- Can’t detect the sample which contain NaN3, because NaN3 inhibits HRP active.
Important notes
- The kit takes out from the refrigeration environment should be balanced 15-30 minutes in the room temperature, ELISA plates coated if has not use up after opened, the plate should be stored in Sealed bag.
- washing buffer will Crystallization separation, it can be heated the water helps dissolve when dilute . Washing does not affect the result.
- add Sample with sampler Each step, And proofread its accuracy frequently, avoids the experimental error. add sample within 5 mins, if the number of sample is much , recommend to use Volley .
- if the testing material content is excessively higher (The sample OD is bigger than the first standard well ),please dilute Sample (n-fold), Please diluente and multiplied by the dilution factor.（×n×5）.
- Closure plate membrane only limits the disposable use, to avoid cross-contamination.
- The substrate evade the light preservation.
- Please according to use instruction strictly, The test result determination must take the microtiter plate reader as a standard.
- All samples, washing buffer and each kind of reject should according to infective material process.
- Do not mix reagents with those from other lots.
